Spatial light modulator having amplitude coupled with binary phase mode

摘要

An SLM rotates linearly polarized incident light, produced by a first polarizer, through a continuous range of angles up to a maximum angle, eg. seventy degrees. The second output polarizer is oriented orthogonally with respect to the angular thirty-five degrees bisector between the first polarization state at zero degrees rotation and the maximum possible angular rotation at seventy degrees and accordingly, a single SLM can be operated in an amplitude coupled binary phase mode.
